NITED STATES HENRY K. CRUIT, OF WASHINGTON, DISTRICT OF COLUMBIA.

EMPROVEMENT IN LA PPING JOINTS FOR PIPES.

Specification forming part of Letters Patent No. 146,65?, dated January20, 1874; application led October 18, 1873.

T0 alt whom it may concern:

Be it known that I, HENRY K. CRUIT, of XVashington city, in the countyof Vlfashing ton and District of Columbia, have invented a new LappingJoint for Pipes 5 and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the aecompanyin g drawin which form part of thisspecification.

Figure l is a side View of my new lappingjoint for pipes. Fig. 2 is alongitudinal section.

Like letters in both figures of the drawing indicate likeparts.

In gas-fitting and plumbing it is frequently found necessary to carr fone pipe across another, which is done by heating and bending the pipeover the crosspipe, or bending it over without heating it, as the casewill admit of, all of which requires a good deal of time and labor toaccomplish successfully withoutbreaking the pipe. Now, the object ofthis invention is to avoid this; and it consists of a lapping joint,77made of malleable iron, brass, or other suitable material, and curved soas to lap snugly over a cross-pipe, and having' a screw itting at eachend to connect with the end of a pipe on each side of the saidcrosspipe, the said joint to be manufactured and sold the same as otherarticles are, for gastters and plumbers use.

A represents the joint suitably curved to lap over a cross-pipe, andmade straight for a short distance from where the curve begins to theends, and provided with screw-threads a a, so as to connect the jointwith the ends of the pipe on the sides of the cross-pipe.`

As hereinbefore mentioned, a good deal of time and expense are requiredto accomplish the crossing of 011e pipe over another, and

made of brass will give a neat nisli to the pipe when left exposed.

Having thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is-

The lapping joint A, having a curve to fit over a cross-pipe, andscrew-ttings c a on the ends for making the proper connections,substantially as shown, and for the purpose set forth.

In testimony that I clailn the lforegoing I have hereunto set my handthis 22d d ay of September, 1873. HENRY K. CRUIT.
